Technical Specifications & Construction
These track rollers feature a nylon body with precise U-groove geometry (8mm inner diameter × 30mm outer diameter × 9mm width), integrated with a standard 608ZZ sealed ball bearing. The nylon material provides resistance to wear and corrosion, while the sealed bearing design incorporates dual shields to help reduce debris ingress.

Functional Design Advantages

U-Groove Profile: Engineered to engage securely with common sliding tracks, maintaining alignment during linear motion.

Sealed Bearing Operation: The 608ZZ ball bearing contributes to consistent rolling performance with reduced maintenance needs.

Lightweight & Non-Marring: Nylon construction minimizes surface damage to tracks and operates quietly compared to metal alternatives.
